Hemoccult Test: What You Need To Know
Fecal Occult Blood Test Overview and Types
A Fecal Occult Blood Test (FOBT) is designed to detect hidden blood in stool. This non-invasive test is utilized to identify early indications of colorectal cancer.
There are two main types of FOBTs:
- guaiac-based
- immunochemical
The guaiac-based FOBT employs a chemical reaction to identify the presence of blood, with a positive result indicated by a change to blue. It is important to note that the outcome can be influenced by certain foods or medications.
On the other hand, the immunochemical FOBT (iFOBT) targets human hemoglobin, a protein found in red blood cells, present in stool. Its specificity to human blood makes it distinct from guaiac tests.
For both tests, individuals are required to collect small stool samples using a kit. These samples are then submitted for analysis.
Purpose, Preparation, and Expectations from Hemoccult Test
The Hemoccult test is a tool used by doctors to check for hidden blood in stool. The presence of hidden blood can be an indicator of various conditions such as polyps, hemorrhoids, or colorectal cancer.
To prepare for the Hemoccult test, it is necessary to avoid certain foods and medicines three days prior to the test. These include:
- Red meat
- Vitamin C supplements
- Aspirin
as they can affect the results.
The test requires the collection of a small sample of stool using a special kit. Samples from two different bowel movements are typically collected on three separate cards.
After collection, the card is returned for analysis. The results can be either positive or negative. A positive result indicates the presence of occult blood in the stool. A negative result indicates that no blood was found.
A positive result necessitates further tests to determine the cause of the hidden blood in the stool.
It is noted that the Hemoccult test does not detect all types of cancers or polyps, and regular screening is essential for comprehensive health monitoring.

Risks and Dietary Restrictions for Accurate Hemoccult Test Results
A hemoccult test is a stool-based screening used to detect hidden blood, indicating conditions like colon cancer or ulcers. The testing process involves minimal risks, as it is non-invasive and does not require anesthesia or sedation. Participants collect stool samples at home using a provided kit. The primary concern is the potential for false positives or negatives, which could lead to further testing or delays in detecting an underlying condition.
Dietary changes are crucial for accurate test results. For three days prior to the test, it is recommended to avoid:
- Red meat (beef, lamb)
- Foods high in Vitamin C (oranges, grapefruit)
- Aspirin
- Other non-steroidal anti-inflammatory drugs (NSAIDs)
These substances can interfere with test accuracy by causing false positives due to bleeding from irritation or false negatives if vitamin C inhibits blood detection.
In conclusion, while the Hemoccult Test carries minor risks primarily related to the accuracy of results, adhering to dietary guidelines is essential for enhancing the likelihood of detecting potential health issues.
Interpreting Hemoccult Test Results
A Hemoccult test is a method used to check for hidden (occult) blood in the stool. It's often part of routine screening for colorectal cancer. Doctors provide a kit for home use to collect samples from several bowel movements.
To interpret the results:
-
Negative Result: A lack of color change on the test card or pad indicates the absence of blood in the stool sample. This result is negative, generally suggesting no further testing or treatment is necessary.
-
Positive Result: A blue color change indicates the presence of occult blood, yielding a positive result. A positive result does not necessarily indicate cancer but indicates the need for further investigation.
In conclusion, understanding Hemoccult test results plays a role in health management.
Colon Cancer Screening Options
Colon cancer screening is essential for detecting early signs of colon cancer, which increases the likelihood of successful treatment.
There are several options for colon cancer screening:
-
The first is a colonoscopy, where doctors use a long, flexible tube to check the entire colon and rectum for abnormal areas, and samples can be taken during this procedure.
-
Another option is the stool-based test, which includes fecal immunochemical tests (FIT) or guaiac-based fecal occult blood tests (gFOBT). These tests look for tiny amounts of blood in the stool, which could indicate the early stages of colon cancer.
-
Additionally, there is the option of CT Colonography, also known as virtual colonoscopy. A CT scanner is used to examine the colon and rectum for any abnormalities without requiring any physical intrusion.
The choice of screening method depends on personal preference, health condition, and family history among other factors. Regular screenings are associated with increased detection rates of colon cancer at an early stage.
